Would it have been sexist if he said that a girl gamer's guy would give her head if she let him win? Or, if he said that a gay gamer's boyfriend would give him a blowjob if he let him win? Or a lesbian gamer's girlfriend would give her head if she let her win? All of those statements are equally ridiculous, all it was was a stupid remark, no hate, misogyny, or sexism attached to it. These kind of thought police will be the death of our society.

Now, if he had said, "Play the game with your dumb whore of a girlfriend, she'll totally suck your cock just for allowing her the gratitude of playing with you..." That would have been misogynistic.
